Abstract
An epoxy group-bearing organopolysiloxane or organosilane is prepared by effecting addition reaction between an organohydropolysiloxane or organohydrosilane and an alkenyl group-bearing epoxy compound in the presence of an addition reaction catalyst. A cyano group-bearing compound is co-present in the reaction system. The end organopolysiloxane or organosilane having a stabilized viscosity is obtained while avoiding gelation or thickening during reaction.
